1 Claim. (0]. 1860) My invention relates to a unitary concrete building wall construction, shown in the accom-' panying drawings and more particularly pointed out and described in the following specification and claim. a l

In the drawings accompanying this specification:

Figure 1 is a sectional perspective view showing the wall in process of formation, with the molds or trays locked in spaced relation to a sheathing, between Which an'd the molds a con-- crete mixture is poured.

Figure 2 is fragmentary perspective view of the concrete wall as it would appear followin the removal of the molds or trays.

Figure 3 is a vertical cross-sectional View through the wall showing the molds or trays Vertically spaced strips of Celotex 4, are interposed between said Celotex sheathing and a second sheathing of Celotex 5, spaced from the first named sheathing to provide an air space 6, between the respective sheathings.

Anchoring devices 7, preferably constructed of a non-heat conducting material, are secured to the outer Celotex sheathing by nails 8, driven through the spaced sheathings 3-5. into the.

studding 2, the anchoring devices serving as abutments for a plurality of sheet'metal molds or trays 9, clamped thereto, in uniformly spaced relation to the outer ordsecond sheathing 5, of Celotex. a

A plurality of trays 9, formed of sheet metal of a suitable depth, are-partially filled with plastic clay l0, which is'then given a coating of semifluid clay ll, of somewhat sticky consistency.

Onto this surface are forced chips of stone l2,

that they may temporarily adhere or be embedded in the clay Ill. lodged in the tray, until.

they later become an integral part of the wall it, developed by pouring concrete between the outer sheathing of Celotex'fi, and the clay Ill, deposited Within the trays.

The semi-fluid clay H, is then sprinkled with powdered stucco M, which later forms the outer finished surface of the walls.

The walls to. of. the sheet metal molds or trays,

have a return bend 912, at their open outer face, which in conjunction with the return bends of adjoining molds or trays forms an indenture l5,

bar.

in the concrete, sometimes called the scratch out which marks the line of demarcation bea tween the blocks of stone.

Respectively connected with the several anshoring devices 7, by removable pins l6, are thin strips of metal ll, having elongated slots It, to receive tapering keys [9, adapted to engage transversely slotted. bars 20, extending across and back of the trays, whereby the walls of the trays are forced into and held in abutting contact with the projecting ends of the anchoring devices I;

v being locked in that position by the tapering keys.

The bars 293, are stepped at one end (2l)as indicated, to avoid any possibility of the lower tapering key contacting the upper end. of the adjacent transverse bar. The tapering keys, l9,

. engaging the underlying end of the bar are bent.

at right angles that they may be more easily removed, and without danger of interference with the overlapping end of the adjacent transverse Extending the openings 23. in the anchoring devices asthe concrete wall developed horizontally and up vertically and horizontally through openings in the anchoring devices 7, are reinforcf inc rods 22 and 22a, which are pushed through wardly; the wall being thus knitted together as an integral, unitary structure. a

To construct a wall the concrete .mixture is poured between the outer Celotex sheathing 5,

and the clayfilled molds 9, in which are temporarily held chips of stone 24, and stucco 25, to

provide a finished surface for the face ofrthewall.

The reinforcin rods 22, 22a, are pushed through t e vertically and horizontally disposed openings" 23, in the anchoring devices 1, as the wall is developed horizontally and vertically. Upon the concrete setting sufiiciently, the molds or trays are removed, beginning at the bottom and working both horizontally and upwardly. Upon the removal of the trays the ends of the thin strips of metal l7, that may project are clipped off and a the surface of the wall is then washed to dislodge any semi-fluid clay that still adheres to its sur face. whereupon the job is finished. While I have described my invention as applied to building wall construction, it is obvious that it is adapted for other concrete construction work. What 'I'claim is: v l

Crete wall. consisting in supporting a plastic clay along one face of the wall of a mold, applying a layer of more fluid clay to the inner surface of the first mentioned clay, applying stucco material and partially embedding the same in both layers of clay, pouring the concrete between the walls of the mold, allowing the same to set and removing the molds and Washing away the clay, leaving the stucco partially embedded in the concrete.
